The Eiffel Tower, the Louvre museum and scores of shops on the Champs-Elysees are set to close as authorities warned Thursday of fresh violence this weekend during protests which have ballooned into the biggest crisis of Emmanuel Macron's presidency. The government is scrambling to stave off another Saturday of burned cars and running street battles with police by "yellow vest" protesters furious over rising costs of living they blame on high taxes. An interior ministry official told AFP that authorities were bracing for "significant violence" on Saturday, based on indications that protesters on both the far right and far left are planning to converge on the capital.
